What is radon gas , and how can it be reduced ? RADON GAS By John Ware

IEE Wiring Matters | Spring 2005 | www.iee.org Radon – a brief explanation Radon is a naturally occurring gas that has no colour, smell or taste. The gas comes from minute amounts of uranium present in all earth materials such as rocks, soil, bricks and concrete. Radon is present in all parts of the UK, but in the most populous areas the levels are quite low. Some of the highest levels are found in the south west, but levels well above average have been found in some other parts of England and parts of Scotland, Wales and Northern Ireland. However, even in these areas most homes have low levels. Maps showing the areas of the country affected by radon are available from the National Radiological Protection Board (NRPB). However, radon can be found in other areas and, even though levels may be low, isolated high levels can occur. The only way to be sure is to conduct a radon test in the building.
